# Overview

## Vultisig Project

Vultisig is an open-source cryptocurrency vault that takes a novel approach: seedless, multi-factor, multi-chain security based on MPC (Multi-Party Computation) technology.

Available on iOS, Android, macOS, Windows, Linux, and as a browser extension—Vultisig delivers multi-sig level security without the traditional multi-sig complexity.

## What is Vultisig?

Vultisig is a multi-chain, multi-factor, multi-platform Threshold Signature Scheme (TSS) vault. No specialized hardware required.

Supporting UTXO, EVM, BFT, and EdDSA chains (Bitcoin, Ethereum, Cosmos, Solana, and 30+ more), Vultisig generates both ECDSA and EdDSA signature keys for every vault. Hold and sign for BTC, ETH, SOL, and more from a single vault setup.

Powered by [DKLS23](https://github.com/silence-laboratories/dkls23), a state-of-the-art TSS protocol developed by Silence Laboratories.

Built by the founders of [THORChain](https://thorchain.org)—creators of the largest and longest-running multi-chain DEX powered by Threshold Signature Schemes.

### Key Features

* **No seed phrases**: Vault shares replace vulnerable 12/24 word seeds
* **Multi-chain**: 30+ blockchains from one vault (Bitcoin, Ethereum, Solana, Cosmos, and more)
* **Multi-factor**: Multiple devices required to sign transactions
* **Multi-platform**: iOS, Android, macOS, Windows, Linux, Browser Extension
* **Open source**: Fully auditable code on [GitHub](https://github.com/vultisig)

## How It Works

Vultisig works like a traditional multisig wallet but with flexible setup options and modern convenience.

**Fast Vault** — Single device + Vultisig server. Quick setup, instant signing.

**Secure Vault** — Multiple devices you control:

* 2-of-2: Fastest setup, no fallback
* 2-of-3: Recommended, with fallback device
* 3-of-4: Maximum security, with fallback device

{% hint style="info" %}
These are the most common configurations, but Vultisig supports a wide range of threshold setups for advanced users.

## Why Vultisig?

**Better security model:**

* Vault shares don't store funds—no funds at risk if you lose a share
* No on-chain registration of signing keys
* Compatible with all chains and fully DeFi compatible (multi-sigs often aren't)

**Uses devices you already own:**

* Phones, tablets, laptops with familiar interfaces
* Secure Enclaves protect vault shares
* Biometric authentication built-in
* Doesn't look like a hardware wallet (better operational security)

**Open source and audited:**

* Fully transparent codebase on [GitHub](https://github.com/vultisig)
* Security audits completed ([view reports](https://docs.vultisig.com/help-and-legal/security))

{% hint style="info" %}
**No registration required.** Vultisig never permanently stores your email or personal info. Fast Vaults briefly require email to send backup files—used once and not retained.
